FIRE PROOF WINDOW.

Specification of Letters Patent.

Patented Oct. 8, 1997.

"Applioation'filed s vsmt raisot. Garlands-342,761.

Be it known that 1, Sims l1. Ponnuor, a citizen of the United States, residing at New Rochelle, inthe ,county of Westchester and State of New York, have invented certain newand useful Improvements in Fire'- proof Windows,

of which the following is a specification. v

" This invention relates to improvements in fireproof windows and refersmorespecifically to' improvements to swinguponhorizontal pivots.

in-the details of construction in'a window of that form in which a sash is pivoted midway ofits vertical length 'Among the salient objects of the invention are to provide a constructionin whieh great accuracy and unifqrmityof fit between the'movable sash and maybe secured, despite inaccuracy of -manufacture,' whereby the sash is made to move with perfecti'free dom yet nevertheless'forins a close weatherproof fit; to provide a construction which while securing the accuracy of fit desired, may be quickly and economically assembled and united; and in general to provide an improved construction of' the character referred to;

In the drawings, Figure 1 is an inside face elevation I of a window' embodying the invention, parts being" broken out-to reduce the size of'the' figure and other parts broken away to -show internal construction; Fig.

I 2 is a transverse or horizontal. sectional view on line 2 -2 of Fig.1 1- and looking downwardly; Fig. 3 is a vertical sectional view taken approximately on line-3+3v of Fig. 1 and looking in the direction'of the arrows;

Fig.4 is ahorizontal sectional view through one side of the casing and movable sash taken on line of Fig. 1 and looking downwardly; Fig. 5 ins similar view taken on line 5-6 and looking downwardly; Fig. 6 is a perspective viewof a fragmentary portion of theside casing member showing particularly the manner .in

which the two-part adjustable side jamb is constructed.

Referringto the drawings, 1 designates as a whole a hollow sheet metal window casing or frame comprising the hollow side frame members 2 5, upper and lower frame members 3 and 4, and an intermediate cross member 5.

The hollow side'frame members 2, 2, are so con structed in other parts which extend above and below the cross frame member 5 as to provide parallel sided relatively deep inwardly facing jamb channels or grooves 6 and 6, best seenin Figs. 4, 5 d 2; It will "benoted that the bottoms of these is b grooves are V-shaped with the apex of, the angle directed in-, 'wardly. In those portions .of the; grooves 6, 6, above the transverse member 5 are seated adjustable jam'b members 7 and 8 (see. Fig. 6), but in the portions of the grooves 6, fiflbelow the member 5 the side bars 9 of the stationary sash 9" are seated directly,-see Fig; 2. .55

The inwardly facing lower side of the top member 3 of the casing is. constructed 'to receive the of the movable sash 10 in such manner as to permit the latter to swing inwardly iii its opening movement, and g to form a close weather-protected joint when the sash is closed; To this end that face 10 of the casing against which the upper side of the top sash rail fits is inclined from-the horizontal slightly in: an upward and inward: direction, an integral lip or overlapping weathering flangegl is formed at the outside of the casing member, a cooperating lip or flange 12 is formed upon the top sash .rail 13 which fits into the recess formed between the lip 11 and the opposed face 10'of the casing, the top rail of the-sash is provided at its inner side with an upwardly extending flange 14 coincident with the inner face or plane of the sash rail which fits against the inner face. 15 of the casing when the sash is closed.

The upper side of the cross frame member 5 which meets the lower rail-16 of the movable sash andfsaid lower rail are constructed substantially like the upper rail and top casing member, except that the lips 11,-

i2 and. flange 14' are in reversed relation topermit the lower edge of the sash to swing-inwardly.

The .movable sash is pivoted ou horizontal pivots,

adjustment, and moreover the axes of the pivots are located well inside of the center of gravity of the sash,

so that the latter will tend to swing shutby gravity when'in partially open position. To this end one memher 18 of each pivot takes the form of about arm having its base rigidly bolted or secured to the inner face of the side rail of the'sash; the socket-engagingend of thearm being arranged to extend parallel with the plane of the sash and to engage a socket ,19 carried by the corresponding casing member 2. The sockets 19 are in the improved construction showneach formed of an inner and outer aperture member, as 20, and 21,

arranged respectively insideand outside of the inner wall 2 of the casing with their apertures in register.

.with other and the interposed wall 2 is also ap .ertur'ed so that the pivot arm extends entirely through the assembled parts. This permits the lateral shifting movement of thelsash, hereinbefore referred to. a Describing now that feature of the present invention which I deem most important, and referring particularly to Figs. 4, 5 and fi, the two parts 7 and 8 of each side jamb are formed-of sheet metal and made approxi- I mately channel-shaped in cross section; the width of the jamb-members being such that they fit snugly within the dorresponding. channel 6 aridlthe inner edges e .of the sides-whidh form the channel -being bent in-.

wardlytowards other and to stand par,

.allel with the corresponding inclined portionsof tlie bottoms of said jambgroove, as indiciited at 22. The

two members 7 and 8, which togetherform each jeinb',

are constructed to telescope upon each other so thatwhenunited they form apractically continuous strucsash and the casing, and which weathering members are necessarily constructed differently above and beits the pivotal axis of the sash. To' these ends one member, that designated 8 in this instance, is provided atone end with tongue-like extensions 8 inset slightly relatively to the plane of the several sides oi the jamb upon which they are formed so thatwhen fitted in the corresponding end of the member '7 the structure will have exteriorly flush surfaces. 'Ihe member 8 is provided with a hook-shaped weathering flange 23 which receives a lip or flange 24 updn the corresponding part of the side stile of the sash The member 7 is provided with-a lip 24 which fits within a hook-shaped weather- 'ingflange 25 formed upon the corresponding part ofthe side stile ofthe sash.

, them and securing them in position, I proceed as follows: The casing frame having been completed, with the exception of seating the jamb members 7 and 8 '25 therein, the frame is most conveniently laid flat upon a suitable table or support'and the jamb members put in place; i Todo this the telescoping ends are adjusted upon each other and the members then flexed upon the as yet unsoldered joint, so that-the upper and lower ,ends of the jaimb can be inserted in the jamb groove 6 at the upper and lower corners of the sash opening. "The two members are then flexed back into alinement 'with each other and into position in' the jamb groove;

, v the telescoping joint being by this movement brought' entirely together. Before fastening the jainb .mem-

bers in position in the jamb groove I place the movable sash-in position 'between the iambs and temporarily support it in properly centered position. I now move the 'jamb' members in their. seats toward .the opposed edges of the sash frame until the jambs closely and evenly approach the sides of the sash at all points but do not actually contact therewith. This is conveniently accomplished by slipping space strips of sheet 3 metalbetween thejambs and sash frameand moving the jambs out into bearing with the spacestrips. Haw

two jamb, membe s 71and 8 nieet. Having thus accurately fitted the jambs; te'the sash, the pivots are applied to the latter and seated'in their respective. soc-l etsg P By-constructiri g the bottoms bf th'e jamb grooves as shown 1 am enabled to make said grooves the proper width with great accuracy and-perfect parallelism, so

that the jamb members will fit accurately therein.

Moreover the'c'otiperating inclined sides of the bottom of the groove and inner edges of the jamb insure that the sides of the jamb will be forced outwardly into bearing with the'sides of the groove; in case the jamb In assembling the parts described, and adjusting member be slightly distorted in its manufacture. The fact that the jamb may be withdrawn slightly from the bottom of the groove in adjusting it to position, as described, does not permit the edges of the jamb to move away from the. sides of the groove enough to be objectionable or prevent the proper union of the parts by the subsequent soldering operation.

The glazing in both the upper and lower sash is inserted in a well known manner; the lateral and upper glazing grooves,'as 26 and 27, being bottomless to perunit the glazing to be shifted both laterally and upwardly in placing it in position and a divided muntiu 28 being employed to, secure the lights in place, in a manner well understood in this art.

The gravity latch mechanism comprising the pivoted and weighted lever 29 upon the upper sash rail of the movable sash and latch 30 upon the casing f'rame, adapted to be disengaged by the lever 29 when the latter is oscillated by the chain 31, form no part per 'so of the present invention. 1

It will be seen from the foregoing description that accomplishthe several objects oi the invention 11mmbefore specified and produce an extremely neat and reliable structure which can be manufactured and assembled with great economy. I

I claim as my invention:
